Christians you must explain

Adam and Eve had 3 sons, Cain, who killed Able, (his brother), and Eve had another son called Seth to replace Able. There was other people on the earth at the time, but the main focus of Genesis is on Adam, Eve, and creation. Not too many references talk about the other humans until AFTER the flood mentioned later on in the bible. When Noah builds the ark, he has 3 sons too, Shem, Hem, and Jeppath. They all 3 have their wives and noah has his wife and those 8 people board the Ark with animals. Its true and once you understand that the bible is NOT WRITTEN IN CHRONOLOGICAL ORDER, you find out the devil, was once named Lucifer in the book of Isaiah and was kicked to earth before Eve gets tempted by him. Then in other older testament books, wich many bibles had removed, theres also talks of Giants, (book of Enoch calls them the Nephilem). Book of Joshua talks about Giants too! Some other old testament facts written down, there was only one language BEFORE the tower of bable , theres unicorns, dinosaurs, and dragons mentioned in some bible texts too..fascinating stuff if you really want explanation 😀

I believe there were other humans created in addition to Adam and Eve. When Cain killed Abel and God sent him out of Eden, he was worried that whoever would find him would kill him. Why was he worried if there were no other humans there?

And several daughters

They had sons and daughters and people lived to be 900 years back old then so they had lots of children

Most creation stories are highly pretentious mind rape. There's no need to discuss them further.
